Mary L. Disis

Mary L. "Nora" Disis is an American physician-oncologist whose research focuses on cancer immunotherapy and cancer vaccines. She is the editor-in-chief of JAMA Oncology and director of the Cancer Vaccine Institute at the University of Washington.

She was part of the scientific team who discovered that the HER2/neu molecule is a tumor-specific marker, or antigen.

Education Disis received her medical degree from the University of Nebraska–Lincoln and completed her residency at the University of Illinois College of Medicine. She received a fellowship at the University of Washington Division of Medical Oncology in 1993. She has board certifications in Internal Medicine (1989) and Medical Oncology (1997).

She received a fellowship at the University of Washington Division of Medical Oncology in 1993. She has board certifications in Internal Medicine (1989) and Medical Oncology (1997).

Disis became interested in medicine and research in high school, becoming "involved in lab-based research projects in college and medical school." She is a member of Sigma Xi. and a member of the Association of American Physicians.

She has previously discussed gender inequity in the science field. She commented on the gender gap and lack of leadership positions for women. In an interview with CoMotion, she discussed mentorship, innovation, and opportunities within biomedical research, noting that she was the only female oncology fellow in her class.

Career Disis is the founder and director of the UW Cancer Vaccine Institute, a member of Fred Hutchinson Cancer Center, editor-in-chief of JAMA Oncology, a deputy editor for JAMA and a past associate dean at the University of Washington School of Medicine. She holds the title of the Helen B. Slonaker Endowed Professorship for Cancer Research, professor of Medicine and Oncology, and adjunct professor of Obstetrics & Gynecology and Pathology. She cofounded the biotechnology company EpiThany, which focuses on cancer vaccine technologies. and served as Principal Investigator from 2007 through 2024.

Disis served as a Komen Scholar for Susan G. Komen from 2012 to 2021, where she participated as a reviewer in Komen's peer review process.

In 2015, she became the founding editor-in-chief of JAMA Oncology, a peer-reviewed medical journal published by the American Medical Association. Under Disis' leadership, the journal launched its first issue in 2015 and became one of the American Medical Association's specialty journals. She is a deputy editor for JAMA. She has previously worked as an editor at the Journal of Clinical Oncology.

On July 1, 2015, she became an American Cancer Society Professor. As an ACS Professor, she served as a spokesperson for the Society. Her research focused on vaccines to prevent colon cancer by identifying proteins that are overexpressed in early stages of the disease. In 2020, her professorship was renewed for another five years.

She is an Athena Distinguished Professor of Breast Cancer Research and has been a Breast Cancer Research Foundation investigator since 2016. In 2016, she was a Chair of the ASCO-SITC Clinical Immuno-Oncology Symposium Program Committee.

Disis has discussed developments in cancer immunotherapy and vaccine-based approaches to treatment. In 2023, CGTLive also reported on her comments regarding investigational immunotherapy approaches, including CAR T-cell therapies being studied for solid tumors.

In 2025, she was among investigators receiving funding support for research on ovarian cancer vaccines through a collaboration between the Rivkin Center and the Andy Hill CARE Fund.

Research HER-2/neu Disis has conducted research on human epidermal growth factor receptor 2 (HER2, also known as ERBB2), a protein that is overexpressed in a subset of breast cancers. Her research has investigated HER2/neu as a tumor antigen and the use of HER2-specific immune responses in cancer treatment.

Disis and her collaborators have investigated vaccines targeting HER2/neu, including peptide-based vaccines and vaccines containing the intracellular domain of the HER2/neu protein. Clinical studies examined whether these vaccines could induce HER2-specific immune responses in patients with cancer.

Disis also participated in research combining HER2 vaccination with adoptive T-cell therapy. A phase I clinical study evaluated HER2/neu vaccine-primed autologous T-cell infusions in patients with advanced HER2/neu-expressing cancers.

In 2011, Newsweek profiled Disis's research on an experimental HER2/neu vaccine for metastatic breast cancer, describing the vaccine as an approach intended to stimulate T-cell responses against HER2/neu antigens expressed by cancer cells.

A later phase I/II clinical trial further evaluated HER2 vaccine-primed autologous T-cell infusions in patients with treatment-refractory HER2-overexpressing breast cancer.

Disis has also led research into DNA vaccines targeting HER2. In a phase I clinical trial published in 2023, she and her colleagues evaluated a plasmid DNA vaccine encoding the intracellular domain of ERBB2 in patients with advanced HER2-positive breast cancer. The study primarily assessed the vaccine's safety and ability to induce immune responses.

In 2022, Axios Seattle reported on Disis's work developing experimental vaccines intended to prevent or treat HER2-positive breast cancer and reported that the research was moving into phase II clinical trials. In 2023, Seattle Met profiled Disis and her research on HER2-targeted vaccines and reported on clinical trials involving vaccines designed.
